Shooting start device and method of internal camera of portable data processing device

Abstract

The application discloses a shooting start device and a shooting start method of an internal camera of a portable data processing device. The shooting start method includes: creating a shortcut icon of the shooting start device on a lock screen of the portable data processing device; starting a shoot thread after the shooting start device is started. The shoot thread includes: A, creating a window on a screen; B, opening the internal camera; C, setting the focal length of the internal camera to be the predetermined focal length; D, interrelating a viewfinder of the internal camera with the created window; E, starting the viewfinder of the internal camera and displaying an image of the viewfinder; F, sending a shooting signal to the internal camera after a shooting instruction is detected; G, staring a background thread or invoking the started background thread, transmitting data of an image shot by the internal camera to the background thread for preservation, and returning to the step E after the shooting thread is completed. By using the shooting start device and the shooting start method of the internal camera of the portable data processing device, times of human-computer interaction operation can be decreased, the operation process is simplified, and shooting speed is improved.

Description

technical field [0001] The present application relates to the technical field of a built-in camera of a portable data processing device, in particular to an apparatus and method for starting and shooting a built-in camera of a portable data processing device. Background technique [0002] Portable data processing equipment generally refers to electronic equipment that has electronic data processing capabilities and is convenient to carry around. For example, mobile phones are mobile phones, personal digital assistants (PDA, Personal Digital Assistant), handheld computers (Pocket PC), tablet computers, etc. The current portable data processing equipment usually has a built-in digital camera, which has the function of taking pictures or video. For example, the current mainstream mobile phones in the industry all have built-in cameras, and users can use the mobile phone to take pictures and video. [0003] With the improvement of the hardware performance of portable data proc...

AI Technical Summary

Problems solved by technology

[0006] Therefore, the existing portable data processing equipment built-in camera startup shooting scheme requires more human-computer interaction operations, cumbersome operations, and lower shooting speed. good time to capture

Moreover, after taking an image, it takes a long time to save the viewfinder to return to the ready-to-shoot state, and the continuous shooting speed is slow, often missing the opportunity to capture
